What is the sum of the first 14 terms of the sequence an = 6n -12

mina [271]

When n = 1 first term = -6
n = 2 second term = 0
n = 3 third term = 6

n = 4 4th term = 12

so we have an Arithmetic sequence first term = -6 and common difference = 6

Sum 14 terms = (14/2)[2*-6 + (14-1)*6]

Solve the following quadratic equation using the quadratic formula.

sdas [7]

$ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a};\ x_2=\dfrac{-b+\sqrt\Delta}{2a}$

<span> $5x^2-8x+5=0\to a=5;\ b=-8;\ c=5\\\\\Delta=(-8)^2-4\cdot5\cdot5=64-100=-36\\\\\sqrt\Delta=\sqrt{-36}=6i$

$x_1=\dfrac{-(-8)-6i}{2\cdot5}=\dfrac{8-6i}{10}=\dfrac{4-3i}{5}\\\\x_2=\dfrac{-(-8)+6i}{2\cdot5}=\dfrac{8+6i}{10}=\dfrac{4+3i}{5}$
